I did look at the games of your post. It is not the point though. I will let you know what I can make of Polgar's N! in a while. Sometimes a loss in a new variation does make it impopular. Let's turn around and expose as much as we can of the truth. For the moment, my Hiarcs is dissecating the game. So, more later.

If I may, I am still looking for games with 6....g5.

Hello,

     While looking for ideas against the anti-Najdorf 1.e4 c5 2.Nf3 d6 3.Bb5+ ; I decided on the more agressive 3....Nc6 (B51). 

The play is very fluid and will suits player of manoeuvre after 4.0-0 Bd7 5.Re1 Nf6 6.c3 a6 7.Bf1 Bg4 and so on. No structural weakness, a fight for the center.

The gambit 7.Bxc6 Bxc6 8.d4 Bxe4 is also a welcome option for black.

So, remained 4.Bxc6+ ; altering the pawn structure. After 4....bxc6 5.0-0 e5 6.c3 ; Grischuk 6....f5 did not appailed to me as being too loosening. Otherwise, white with a push of d4, opening the center, both black doubled c  pawns would be cause of concerns. 

Comes J.Polgar (as black) against Kasparov : 6....g5 (!?). As I understand it it was a rapid game, but what a game.

And then, in one independant DB I found that treasure, which hopefully will get you sharing similar fights here :
